2007 PONTIAC GRAND PRIX coolant temperature

The vehicle’s hood is open.
The hazard warning ashers are on.
There is an emission control system
malfunction.
The engine coolant temperature is too high.
The oil pressure is low.
Two remote vehicle starts have already been
provided for that ignition cycle.
If a remote start is attempted and is unsuccessful,
the Driver Information Center (DIC) will display
REMOTE START DISABLED.
Vehicles that have the remote vehicle start feature
are shipped from the factory with the remote start
system enabled. The system may be enabled/
disabled through the DIC. See “REMOTE START”
underDIC Controls and Displays (Base Level DIC)
on page 186orDIC Controls and Displays (Uplevel
DIC with Trip Computer) on page 190for additional
information.
Remote Start Ready
If your vehicle does not have the remote vehicle
start feature, it may have the remote start
ready feature. This feature gives you the ability tolock or unlock your vehicle from about 492 feet
(150 m) away and allows your dealer to add
the manufacturer’s remote vehicle start feature.
See your dealer if you would like to add the
manufacturer’s remote vehicle start feature to
your vehicle.
Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out of a
moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)

2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If
the vehicle starts briey but then stops again,
do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transaxle gently until the
oil warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with
your dealer. If you do not, your engine might
not perform properly. Any resulting damage
would not be covered by your vehicle’s
warranty.Engine Coolant Heater
The vehicle may be equipped with an engine
coolant heater. In very cold weather, 0°F (−18°C)
or colder, the engine coolant heater can help.
The vehicle will start easier and get better
fuel economy during engine warm-up. Usually, the
coolant heater should be plugged in a minimum
of four hours prior to starting the vehicle. At
temperatures above 32°F (0°C), use of the coolant
heater is not required. Your vehicle may also
have an internal thermostat in the plug end of the
cord. This will prevent operation of the engine
coolant heater when the temperature is at or above
0°F (−18°C) as noted on the cord.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located above the engine
air cleaner/lter. SeeEngine Compartment
Overview on page 346for more information on
location.
3. Plug the cord into a normal, grounded
110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug
and store the cord as it was before, making
sure to keep it away from moving engine parts.
If this is not done, the cord could be damaged.
How long should the coolant heater be kept
plugged in? The answer depends on the outside
temperature, the kind of oil that is in the vehicle,
and some other things. Instead of trying to list
everything here, we ask that you contact your
dealer in the area where the vehicle will be parked.
The dealer can give you the best advice for that
particular area.
Active Fuel Management™
Your vehicle’s engine may be equipped with
Active Fuel Management™. This system allows
the engine to operate on either all or half of
its cylinders, depending on your driving conditions.
When less power is required, such as cruising
at a constant vehicle speed, the system will
operate in the half cylinder mode, allowing your
vehicle to achieve better fuel economy. When
greater power demands are required, such
as accelerating from a stop, passing, or merging
onto a freeway, the system will maintain
full-cylinder operation.

Enhanced Traction System
Warning Light
If the vehicle has the
Enhanced Traction
System (ETS), this light
may come on for the
following reasons:
If the traction control button located on the
center console is pressed, turning the system
off. This light will come on and stay on. To turn
the system back on, press the button again and
the warning light should turn off. SeeEnhanced
Traction System (ETS) on page 293.
If the system is affected by an engine-related
problem, the system will turn off and the
warning light will come on.
If the light comes on and stays on for an extended
period of time when the system is turned on,
the vehicle needs service.
Engine Coolant Temperature
Warning Light
This light indicates that
the engine coolant has
overheated or the
radiator cooling fan is
not working.
If the vehicle has been operating under normal
driving conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as
possible.
SeeCooling System on page 366for more
information.
179

Engine Coolant Temperature Gage
The vehicle has a gage
that shows the engine
coolant temperature.
If the gage pointer moves into the shaded area,
the engine is too hot. That reading means
the engine coolant has overheated. If you have
been operating the vehicle under normal
driving conditions, you should pull off the road,
stop the vehicle, and turn off the engine as soon
as possible.
SeeCooling System on page 366for more
information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.
